yes, I think I have waited too little after each reboot ...... and given too much importance to errors.
I was wondering why with the default values, instead of about 625-6 Mhz on all 3 with bitmain, it starts with values like 631-658-675, I thought that maybe the firmware increases the frequencies of the best cards .... but it is strange ..... because the order is always similar (the first the worst and the last the best, strange not?).
ckpool results should coincide with the actual hashrate no? maybe after 1 hour of mining ...

Questions:
the default configuration of braiins set the frequency different for every card, Is this difference good to maintain to optimize mining?
